GARRETT BURNS, or CANANDAIGUA, NEW YORK.

MACHINE r03 sPREADIivG ROAD-SUBFACING MATERIAL.

To all whom it may concern:

Be it known that I, GARRETT BURNS, a citizen of the United States,residing at Canandaigua, in the county of Ontario and State of New York,have invented certain new and useful Improvements in Machines forSpreading Road-Surfacing Materials, of which the following is aspecification.

The invention has relation to spreading machines being designed mostespecially to provide a machine for scattering material broadcast uponroadways when it is required to surface the same either when makingrepairs orwhen constructing and finishing a roadway. I

The invention provides a machine which may be propelled over'a roadwayand which during its travel scatters or distributes'material over'theroad to form the surface thereof, such machine embodying means forregulating the delivery of the material according to the condition ofthe surface of the road or to meet conditions encountered in thesurfacing of the road. I

A further purpose of the invention is the provision of a machineembodying a comparatively few number of parts and which in operation iseffective'and capable of being easily manipulated andthrown into or outof action and at the same time admitting of the delivery being regulatedor entirely cut off.-

With these and other objects in view. which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly claimed. Inthe accompanying drawings has'been illustrated a simple and preferredform of the invention, it being, however, understood that no'limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theinvention as claimed may beresorted to when desired.

Referring to the drawings, Figurel isa top plan view of a machineembodying the invention; Fig. 2 is a vertical central longi-v tudinalsection. Fig. '3 is a transverse section on the line 3-3 of-FigQ. Fig. 4is an enlarged detail view of the meansforvthrowing the mechanism intoand out of action. a 51 a d lview at Pers P5 1 Specification of LettersPatent. te te v; 30,1915

longitudinal shaft, the pinion mounted thereon and the lever forshifting the pinion.

' Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

In its general outline the'machine presents the appearance of a wagonand comprises a body and running gear. The body of the machineconstitutes in effect a hopper for re ceiving the material to besupplied to the surface of'the road to be treated or repaired. Asillustrated the body of the machine consists of side pieces 1, front andrear end pieces 2 and 3, respectively, and a bottom comprisingoppositely inclined end sections 4 and 5 and an intermediate horizontalsection 6. The lower ends of the sections 4 and 5 arespaced apart toform a discharge opening 7 which registers with a corresponding opening8 formed in the horizontal section 6. Guides 9 are located upon theunder side of the section 6 adjacent the ends thereof and support acut-off 10 by. means of which the discharge opening 8 is adapted to beregulated or entirely closed. The cutofl 10 is adapted to be moved andheld in the adjusted position by any suitable meansand for convenience alever 11 is mounted upon the front end piece 2 and isdisposed-vertically and extends within convenient reach of the driver soas to be readily manipulated. A guide bracket 12 projects forwardly fromthe end piece 2 and receives the upper portion of the lever 11. Theguide bracket is toothed and a dog 13 mounted upon the lever 11 isadapted to engage'the' toothed portions of the guide bracket and securethe lever and the cut-off in the required adjustedposition. A hand latch14 mounted upon the lever 11 is connected with the dog 13 to admit ofoperating such dog in a manner well understood. Connecting bars 15 areattached at their forward ends to the lower end of the lever lland.extend rearwardly and are attached to the'cut-off 10. The bars 15 arerearwardly diverged so as to insure like movement'of'the cut-offthroughout its length and prevent binding'thereof in the guides 9, ,Theforward ends, of the bars 15 pass through a vertical slot 16 formed inthe lower portion of the end piece 2, thereby assisting materially inpreventing lateral movement of the lever. 1

e The body of the machine is provided with about a vertical axis forpurposes of steer-- ing. A pole or tongue 19 is connected to the axle 17and is adapted to have the team hitched thereto for drawing the machineover the road. A hammer strap 20 connects the axle 17 at a middle pointwith the forward portion of the section 6. The axle 17 is provided withsupporting wheels 21 which are. smaller than the rear wheels so as toturn under the front portion of the body, the forward ends of the sidepieces 1 being cut away at their lower edges for such purpose. The rearaxle 18 is provided with supporting wheels 22 one of which constitutesthe driver for operating the distributing hand or shaking table.

-Beneath the body of the machine is disposed a pan or table 23, the samebeing suspended in a manner to admit of a shaking or vibratory movementbeing imparted thereto for leveling the material and insuring abroadcast delivery thereof. This pan is disposed below the intermediatesection 6 of the bottom and inclines in the direction of its length in arearward and downward direction so as to facilitate the movement of thematerial thereover. A rim extends upwardly from the sides and front ofthe pan to prevent the material from wasting thereover. The pan issuspended at its front end 'by means of an adjustable connection 24,thereby admitting of the inclination of the pan being regulated to suitthe nature of the material and the grade of theroad. Thisconnection 2eis disposed midway of the sides of the pan and constitutes an axis aboutwhich the pan oscillates in its shaking or vibratory movements. Links 25support the rear portion of the pan and are connected at their upperends-with the body of the machine. These links are located near thesides of the pan and serve to hold the same level at all times. The panis adapted to have a lateral vibratorv movement imparted thereto whichresults in leveling or distributing the material throughout the width 1of the pan with the result that such material is delivered upon the roaduniformly.

It is to be understood that a shaking movement may be imparted to thepan in any manner and such'movement is essential in order to obtain auniform distribution of the material over the pan and a positive feed ofthe material therefrom. As shown one of the rear wheels 22 is utilizedas a driver and a gear wheel 26 is secured thereto. A longitudinal shaft27 disposed at one side ofthe machine andmounted a hearing 28 has acrank wheel 29 at its forward end and it's rear end is provided withapinion 30 which is mounted on such to mate thereon so as as be teed-weinto out of meshing engagement with the teeth of the gear wheel 26. Alever 31 mounted upon a side of the body has its lower end inengagement' with the pinion 30 to admit of moving such pinion eitherinto or out of engagement with the teeth of the gear wheel 26. The lever31 is provided with the usual hand latch 32 arranged to coiiperate witha toothed'segment 33 for holding the lever and the pinion 30 in therequired adjusted position. A pitman 3 1connects the crank 29 with thepan 23. The bearing 28 is formed at one end of a cross piece 35 which isarranged beneath the rear portion of the body and attached to the sidepieces 1. The

cross piece 35 serves in a measure to brace and strengthen the body aswell as forming a support for the crank shaft 27; a

In. the operation of the machine'the material, such as sand, gravel orthe like to be applied to the surface of the road is placed in the.hopper or body and the machine is propelled over the road in any manner.The

cut-off 1O is opened'more or less by manipulating the lever 11 so as toobtain proper delivery of the material. lVhen the material is in motionand the pinion 80 is in mesh with the gear wheel 26, the pan or table 23receives a lateral vibratory or shaking movement, thereby agitating thematerial delivered thereon from the hopper or body. This movement of thepan insures a positive and uniform delivery of the -material which dropsfrom the pan upon the road. When it is required to stop the delivery ofthe material, the lever 1l may be manipulated to move the cut-off 10 soas to close the discharge opening 8 or the lever 31 may be operated todisconnect-the crank shaft 27 from the drive wheel. Either one or bothof such operations maybe effected without stopping the forward movementof the machine. It is also observed that the delivery of the materialmay be regulated while the machine is advancing so that portions of theroad may be supplied with less material for surfacing than otherportions according to the condition of the road.

According to the nature-of the material employed it has been founddesirable to vary the shaking movement of the pan. This is accomplishedby providing the crank wheel 29 with a wrist pin 36 which is adjustableto different distances from the center of the crank wheel. A pluralityof openings 37 are formed in the crank wheel 29 at different distancesfrom the center thereof to receive the wrist pin 36. The wrist pin maybe secured in the adjusted position in any approved way. I I I Havingthus described the invention, what is" claimed as new, is': H

:15 In a ma'clrine for applying material to the surface of "aroad, abody having a disusage opening; supporting wheels therefora laterallyshaking pan disposed below the body in position to receive the materialtherefrom, a longitudinal shaft at one side of the body, a pitman andcrank connection between such shaft and pan, a gear'wheel connected withone of the supporting wheels of the body, and a pinion splined to thelongitudinal shaft and movable thereon into or out of meshing relationwith the said gear wheel. i

2. A machine of the character specified comprising a body formed ofinclosing ends, parallel sides, and a bottom, embodying oppositelyinclined sections with their lower ends spaced apart to form a dischargeopening, the side pieces being cut away at their forwardends below thefront bottom section, front and rear supporting wheels, the

front wheels being adapted to turn under the side pieces of the body, ashaking pan suspended beneath the body and inclined rearwardly anddownwardly, connecting means between the shaking pan and one of the rearwheels to admit of a lateral vibratory movement being imparted to thepan, a cut-off for regulating the discharge opening, and an operatinglever mounted upon the front of the body and having connection with thecut-off for moving the same.

In testimony whereof I aflix my signature in presence of two witnesses.
